Description

Pentagonal lower punching screw with pillar

Technical Field

The utility model relates to a screw technical field specifically is pentagonal area post lower impact screw.

Background

In the building field, a plurality of components are connected by using screws, the commonly used screws mainly comprise screw heads, screw rods and tail tips, spiral threads are arranged on the screw rods and the tail tips, the tail ends of the tail tips can be in the forms of pointed tails or drill tails and the like, the screw heads of the screws are placed in sleeves, axial pressure and radial rotating force are applied to the screws through a power device, the screws can be rapidly drilled into target objects, the components of the building are deviated under the influence of various internal stresses in the use process after the building is completed, and can often bear the action of external force such as typhoon and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pentagonal belt post down stroke screw possesses the screw and criticizes the mouth entry when screw head type and cell type can be used for locking the screw when using, and has the advantage that the function was prevented tearing open in the theftproof after the installation, has solved the screw and has criticized the mouth entry when using because screw head type and cell type are asymmetric, and can't be used for locking the screw, and do not have the theftproof after the installation and prevent tearing open the problem of function.

In order to achieve the above object, the utility model provides a following technical scheme: pentagonal belt post lower punch screw, including the screw head, the left side of screw head has been seted up and has been taken the post groove, the center department of taking the post groove is provided with and takes the post, the right side fixedly connected with screw rod of screw head, the right-hand member of screw rod is provided with the tail point, the surface of screw rod is provided with the screw thread.

Preferably, the belt post groove is in a pentagram shape and is designed for an R angle.

Preferably, the thread can match multiple types of tooth types, such as self-tapping or mechanical teeth.

Preferably, the screw head is circular, and the diameter of the screw head is larger than that of the screw rod.

Preferably, the diameter of the screw head is twenty to thirty millimeters, and the diameter of the screw rod is five to ten millimeters.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses two dashes of special design's pentagram area post, the shaping goes out to prevent tearing open and pleasing to the eye pentagram area post groove, through set up in pentagram center department takes the post, can prevent to criticize the mouth in the market commonly used and use, special design's R angle plays the theftproof and prevents tearing open the effect, setting through the screw thread, can match many types of tooth form, for example, from attacking tooth or mechanical tooth etc., through screw head type and cell type, criticize the mouth entry when can be used for locking the screw, solved the screw simultaneously because screw head type and cell type asymmetry when using, criticize the mouth entry when unable being used for locking the screw, and do not have the theftproof after the installation and prevent tearing open the problem of function.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a left side view of the screw head of the present invention.

In the figure: 1 screw head, 2 with column groove, 3 with column, 4 screw rod, 5 tail tip, 6 screw thread.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a pentagonal pillar-equipped down-impact screw includes a screw head 1, the screw head 1 is circular, the diameter of the screw head 1 is larger than that of a screw rod 4, a pillar-equipped groove 2 is formed on the left side of the screw head 1, the pillar-equipped groove 2 is pentagonal and is designed for an R-angle, a pillar 3 is disposed at the center of the pillar-equipped groove 2, the screw rod 4 is fixedly connected to the right side of the screw head 1, the diameter of the screw head 1 is twenty mm to thirty mm, the diameter of the screw rod 4 is five mm to ten mm, a tail tip 5 is disposed at the right end of the screw rod 4, a thread 6 is disposed on the surface of the screw rod 4, the thread 6 can be matched with various types of teeth, such as self-tapping or mechanical teeth, a specially designed pentagonal pillar-equipped with a second punch, the pentagonal pillar-equipped with a pillar 2 is formed, the pillar 3 is disposed at the center of the pentagonal pillar, so as to prevent the use of a lot in the market, the specially designed R angle plays the theftproof and prevents tearing open the effect, through the setting of screw thread 6, can match many types of tooth types, for example from tapping tooth or mechanical tooth etc. through screw head type and cell type, criticize the mouth entry when can be used for locking the screw, solved the screw simultaneously because screw head type and cell type are asymmetric, criticize the mouth entry when unable being used for locking the screw, and do not have the theftproof after the installation and prevent tearing open the problem of function.

In summary, the following steps: this pentagonal belt post lower punch screw through screw head 1, take the cooperation of post groove 2, screw rod 4, tail point 5 and screw thread 6, has solved the screw because screw head type and cell type are asymmetric when using, criticizes the mouth and enters the mouth when unable being used for the lock-matching screw, and does not have the problem of theftproof anti-dismounting function after the installation.
